Constantine is walled, the extant medieval wall having been largely constructed out of Roman material. Through the centre from north to south runs a street (the rue de France) roughly dividing Constantine into two parts. The place du Palais, in which are the palace of the governor and the cathedral, and the kasbah (citadel) are west of the rue de France, as is likewise the place Negrier, containing the law courts. The native town lies chiefly in the south-east part of the city. A striking contrast exists between the Moorish quarter, with its tortuous lanes and Oriental architecture, and the modern quarter, with its rectangular streets and wide open squares, frequently bordered with trees and adorned with fountains. Of the squares the place de Nemours is the centre of the commercial and social life of the city. Of the public buildings those dating from before the French occupation possess chief interest. The palace, built by Ahmed Pasha, the last bey of Constantine, between 1830 and 1836, is one of the finest specimens of Moorish architecture of the 19th century. The kasbah, which occupies the northern corner of the city, dates from Roman times, and preserves in its more modern portions numerous remains of other Roman edifices. It is now turned into barracks and a hospital. The fine mosque of Sidi-el-Kattani (or Salah Bey) dates from the close of the 18th century; that of Suk-er-Rezel, now transformed into a cathedral, and called _Notre-Dame des Sept Douleurs_, was built about a century earlier. The Great Mosque, or Jamaa-el-Kebir, occupies the site of what was probably an ancient pantheon. The mosque Sidi-el-Akhdar has a beautiful minaret nearly 80 ft. high. The museum, housed in the hotel de ville, contains a fine collection of antiquities, including a famous bronze statuette of the winged figure of Victory, 23 in. high, discovered in the kasbah in 1858. A religious seminary, or medressa, is maintained in connexion with the Sidi-el-Kattani; and the French support a college and various minor educational establishments for both Arabic and European culture. The native industry of Constantine is chiefly confined to leather goods and woollen fabrics. Some 100,000 burnouses are made annually, the finest partly of wool and partly of silk. There is also an active trade in embossing or engraving copper and brass utensils. A considerable trade is carried on over a large area by means of railway connexion with Algiers, Bona, Tunis and Biskra, as well as with Philippeville. The railways, however, have taken away from the city its monopoly of the traffic in wheat, though its share in that trade still amounts to from L400,000 to L480,000 a year.
